General Monostable integrated power control circuit, U2100B, used according mode selection relay's triac's applications. Beyond that, used triacapplication wire system power switch, (being load series switch) whereas supply voltage control unit gained from phase rest angle (amin-operation). three wire switch, modes operations possible: Zero voltage switch operation triac control Static operation relay control
Mode Selection Supply Voltage
Operation modes selected external voltage sync. input (clamping). Mode selection determines current requirement driver stage relay's triac's hence selection supply voltage.

AND-connected, identical inputs determine trigger conditions monostable time stages, i.e., both inputs must position "ON" that output switched tracking time starts after trigger conditions elapsed. output state given until tracking time over. Input simple comparator whereas input built window discriminator. Noise suppression guarantee, that there peak noise signals inputs which could trigger circuit. same time, retrigger delayed duration (tOFF), avoid noise signal trigger relay. VRef
